If you are wondering how to apply for peer review at ICAI, the first step is to understand your practice unit's eligibility and prepare the information required for Form 1. The Institute of Chartered Accountants of India (ICAI) has made the Peer Review Board's online portal available for Practice Units to initiate the application process.
The application begins with Form 1 – Application cum Questionnaire, which collects information about the firm's constitution, partners, branches, assurance engagements, and quality control procedures. The questionnaire also includes Part C relating to the Audit Quality Maturity Model (AQMM) V2.0, wherever applicable.
In this guide, we explain the ICAI peer review requirements, how to complete Form 1, the online application process, the information you should keep ready, and what happens after submission.
What Is ICAI Peer Review?
ICAI Peer Review is a quality assurance mechanism through which the professional work and systems of a chartered accountant's practice unit are examined by an independent peer reviewer.
The main objective is to check whether the practice unit:
- Complies with applicable technical, professional, and ethical standards.
- Maintains appropriate systems and procedures for conducting assurance engagements.
- Follows suitable quality control practices.
- Maintains proper documentation to demonstrate the quality of its professional work.
The Peer Review Board (PRB), which is established by ICAI, oversees the process, appoints peer reviewers, and considers their reports before deciding on the issuance of a Peer Review Certificate.
Peer review is governed by the Peer Review Guidelines, 2022, which came into effect on 1 October 2022.
You can read the official ICAI Peer Review Guidelines, 2022, through the PRB portal.
1. Why Is Peer Review Required?
Peer review helps improve the quality and consistency of assurance services provided by chartered accountants.
It encourages CA firms to maintain proper documentation, follow professional standards, and establish suitable quality management procedures.
It also helps identify gaps in a firm's existing practices so that corrective measures can be taken.

2. Peer Review vs Statutory Audit
Although both involve examining professional work, statutory audits and peer reviews serve different purposes.
| Basis | Statutory Audit | Peer Review |
| Main purpose | Examine a client's financial statements | Evaluate the quality of a practice unit's assurance work and systems |
| Subject | Client's financial statements and records | Practice unit's professional work and quality controls |
| Conducted by | Statutory auditor | Independent peer reviewer appointed through the PRB process |
| Focus | Whether financial statements present a true and fair view | Compliance with applicable professional standards and quality procedures |
| Outcome | Audit report | Peer Review Report and, subject to Board approval, Peer Review Certificate |
For a better understanding of the statutory audit process, read our guide on Company Audit: Process, Types, and Importance.
Who Needs to Apply for ICAI Peer Review?
ICAI Peer Review requirements apply to practice units falling under the categories specified in the Peer Review Guidelines and the Peer Review Mandate.
The mandate was introduced in phases to extend peer review coverage to different categories of practice units.
The applicability of the phases has been revised through subsequent ICAI announcements. Therefore, firms should refer to the latest announcement instead of relying only on the original implementation dates.
1. Mandatory Peer Review Categories
The four phases of the mandate cover the following categories:
| Phase | Practice Units Covered | Current Implementation Date |
| Phase I | Practice Units proposing to undertake statutory audits of enterprises whose equity or debt securities are listed in India or abroad | 1 April 2022 |
| Phase II | Practice Units proposing to audit specified large unlisted public companies, or Practice Units rendering attestation services with five or more partners | 1 April 2024 |
| Phase III | Practice Units proposing to audit specified entities that raised funds exceeding ₹50 crore, or Practice Units rendering attestation services with four or more partners | 1 July 2025 |
| Phase IV | Practice Units proposing to audit branches of public sector banks, or Practice Units rendering attestation services with three or more partners | 31 December 2026 |
Important: ICAI announced on 31 December 2025 that Phase IV, which was earlier scheduled to become applicable from 1 January 2026, was extended to 31 December 2026. The Phase III implementation date was also revised to 1 July 2025 through the announcement dated 22 January 2025.
Firms should check the applicable conditions, including the nature of assurance services and the relevant partner count, before deciding whether they fall under a mandatory category.
Refer to the ICAI Peer Review Mandate and the latest announcements for the applicable conditions and amendments.
2. Can a CA Firm Apply for Voluntary Peer Review?
Yes. A practice unit can apply for peer review voluntarily, even if it is not covered under the mandatory categories, subject to the applicable provisions of the Peer Review Guidelines.
Voluntary peer review can help a firm assess its quality control procedures and identify areas that need improvement.
3. What About Newly Established CA Firms?
ICAI also recognises a separate category called a New Unit under the Peer Review Guidelines.
A practice unit established for less than 12 months immediately before the receipt of its application may apply under the New Unit category, subject to the additional conditions prescribed by the Board.
New Units should not automatically select the voluntary category. They should check the specific eligibility conditions applicable to them.

The portal and current instructions should be treated as the reference for submitting the application.
What Happens After Submitting Peer Review Form 1?
Submitting Form 1 initiates the peer review process. The application is followed by the appointment of a peer reviewer, examination of the practice unit's work, and submission of the reviewer's report to the Board.
Here is an overview of the subsequent stages.
1. Appointment of the Peer Reviewer
The Peer Review Board processes the application and appoints a peer reviewer in accordance with the applicable procedure.
The appointed reviewer communicates with the Practice Unit and follows the prescribed reporting and confidentiality requirements.
2. Acceptance by the Peer Reviewer – Form 2
Form 2 is the Acceptance cum Declaration of Confidentiality submitted to the Practice Unit by the Peer Reviewer. It records the reviewer's acceptance and declaration relating to confidentiality.
3. Review Planning and Office Visit – Form 5
Form 5 is the notice issued by the peer reviewer for visiting the office of the practice unit. The reviewer communicates the proposed visit and the relevant review arrangements.
The Practice Unit should keep its engagement records and supporting documentation organised for examination.
4. Additional Information – Form 6
If the reviewer requires additional information or clarification, Form 6 may be used to request it from the Practice Unit. Responding accurately and promptly helps the review proceed smoothly.
5. Examination of Assurance Engagements
The peer reviewer examines selected assurance engagement records and the firm's quality control practices.
The review may involve examining working papers, engagement documentation, relevant reports, and evidence of compliance with applicable professional standards.
The purpose is to assess whether the Practice Unit has followed appropriate professional procedures and maintained adequate documentation.
6. Additional Time – Form 7
If additional time is required to complete the peer review, Form 7 provides for a joint application by the Practice Unit and the Reviewer to seek an extension. The extension is subject to the applicable Board procedure.
7. Submission of the Reviewer's Report – Form 9
After completing the review, the peer reviewer prepares and submits the report to the Peer Review Board using the prescribed reporting format.
The Board considers the report and takes the necessary steps regarding the issuance of the Peer Review Certificate.
8. Issuance of the Peer Review Certificate
After considering the reviewer's report, the Board may issue a Peer Review Certificate if the applicable requirements are met. The certificate is issued by the Peer Review Board, not independently by the reviewer.
For the applicable certificate validity and extension requirements, refer to the Peer Review Guidelines and official reporting formats.
ICAI Peer Review Fees and Processing Timeline
The peer review fee and the time required to complete the process depend on the applicable requirements, the practice unit's information, and the review arrangements.
1. ICAI Peer Review Fees
The Practice Unit should discuss and confirm the applicable professional fee with the appointed peer reviewer.
The Handbook on Peer Review Forms includes an undertaking by the Practice Unit to pay the Peer Reviewer within seven days of receiving the invoice.
The applicable cost and fee-related information should be checked through the PRB's official formats and cost information. Avoid relying on old fee figures published in third-party articles because the applicable arrangements may change.
2. How Long Does the Peer Review Process Take?
There is no single completion time that should be assumed for every practice unit. The time required can depend on:
- Completeness of Form 1.
- Availability of the appointed peer reviewer.
- Number and nature of assurance engagements.
- Availability of engagement records.
- Time taken to respond to queries.
- Any extension required during the review.
